The part number is 2804.140 for the Eibach Pro kit. They sell them in Jegs for $250. I put them in my 89 Shelby Daytona a few years ago and was disappointed that the ride height didn't change but the ride stiffness changed a lot. It handles way better with the stiff springs but it's hard to find a strut that will match the spring rate. I have KYBs and they bounce too much. You really need the Koni's to match the springs but the KYBs work if you can't find Koni's.
